So I started by slapping some Gesso all over the centre of the hessian and spreading it out thinly. This left the pale base I wanted but with that lovely texture.
Next I cut a heart shape from the corrugated card and painted the raised pieces with wite acrylic before inking and distressing the edges. I think I actually painted or gessoed just about everything before I stuck it down!
Under the heart was a spritz or two of blue, and a couple od paint drips of pink. I also did this in the top corner to balance it out.
